Why are the struggles of Christians important according to the Bible?

The Bible emphasizes that the struggles Christian believers face serve a purpose in their spiritual growth. The name Naphtali, meaning 'my wrestling,' closely relates to this idea found in Genesis 30:8. Just as Rachel experienced internal conflict between her old nature and new identity, Christians confront ongoing spiritual battles. Such struggles compel believers to rely on Christ, actively putting off the old self and recognizing their dependency on His righteousness. This process is integral to sanctification, helping believers to grow in grace and knowledge of the Lord.
